Adds a request sink pad to disable dvdspu blending and output the supictures on
a seperate YUV buffer

This is made to enable hardware blending of supictures on platforms with
hardware decoding (such as with flugdlsink on the Intel CE platforms). The
behavior stays the same as before if the request pad is not created.

Pipeline to test using a DVD with SPUs
